=head1 NAME

Image::ExifTool::GeoTiff - Read GeoTiff meta information

=head1 SYNOPSIS

This module is loaded automatically by Image::ExifTool when required.

=head1 DESCRIPTION

This module contains definitions required by Image::ExifTool to interpret
GeoTiff meta information.  GeoTiff information is used in images to specify
exact geometric mappings used to transform the image to real world
coordinates.
